Arsenal boss Wenger said: "We know we face the favourites of the competition. We have belief because we have only had big games in the Champions League and the FA Cup - Tottenham and Liverpool.

"Since the start of this season we have known we have had to be 100 per cent for every game. I believe we can do it but that is down to tomorrow.

"Last year, I believe we went out on the away goal. That shows you it is important it is not to concede at home. But we are in a much better mental shape than a year ago. We lost to Blackburn in the cup and it was a big disappointment - whereas this time we won. And we are really determined to win tomorrow.
